Duplex Stainless Steel ua li cas?
Duplex Stainless Steel ua li cas?
Duplex Stainless Steel (DSS) muaj cov yam ntxwv ua tau zoo heev. Nov yog qee qhov ntawm nws cov yam ntxwv tseem ceeb:
Lub zog txhua yam: Duplex stainless hlau yog ob zaug muaj zog li zoo tib yam austenitic stainless hlau, uas ua rau nws ua tau zoo dua hauv cov ntawv thov uas xav tau kev ntxhov siab ntau dua. Kev tiv thaiv corrosion zoo heev: Vim nws qhov tshwj xeeb microstructure, duplex stainless hlau muaj kev tiv thaiv corrosion ntau dua li cov qib stainless hlau xws li 304 thiab 316, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chlorine. Kev nyuaj siab corrosion kuj zoo: Duplex stainless hlau muaj siab tiv thaiv kev ntxhov siab corrosion tawg los ntawm chloride ions thiab yog tsim rau hnyav ib puag ncig xws li marine thiab tshuaj industries. Tsawg coefficient ntawm thermal expansion: Duplex stainless hlau muaj qis coefficient ntawm thermal expansion piv rau austenitic stainless hlau, uas yog ib qho tseem ceeb nyob rau hauv daim ntawv thov nrog loj kub hloov.
Kev Txuag Nqi: Txawm hais tias kev nqis peev thawj zaug yuav siab dua, kev hloov pauv thiab kev saib xyuas cov nqi tuaj yeem txuag tau ntev vim nws cov kav ntev ntev thiab kev saib xyuas qis dua. Kev ua haujlwm vuam zoo: Duplex stainless hlau muaj cov yam ntxwv zoo vuam, tab sis nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas cov txheej txheem vuam tsim nyog thiab xaiv cov khoom kom tsis txhob muaj embrittlement lossis lwm yam teeb meem thaum lub sij hawm vuam txheej txheem. Lub zog siab ua ke nrog zoo toughness: Duplex stainless hlau tsis yog tsuas yog muaj zog tab sis kuj muaj zog toughness, uas tso cai rau nws ua tau zoo nyob rau hauv kev cuam tshuam thiab ceev loading. Machinability: Txawm hais tias duplex stainless hlau yog qhov nyuaj rau tshuab, lawv tseem tuaj yeem txiav, tsim, thiab tshuab nrog cov cuab yeej tsim nyog thiab cov txheej txheem. Kev qaug zog zoo: Vim tias qhov sib xyaw ntawm nws cov microstructure, kev qaug zog ntawm duplex stainless hlau nyob rau hauv cyclic loading yog zoo dua li ntawm cov hlau tsis zoo tib yam. Environmentally Friendly: Vim nws cov kav ntev, duplex stainless hlau txo qhov zaus ntawm cov khoom hloov, yog li txo qhov cuam tshuam rau ib puag ncig.
